Can I gently ask you which pinmux setup do you use to test your patch ?

I am trying to make uart4 working on a am3517 with mainline kernel(3.3+, your patch is merged). However, on my board the uart4 pins areshared with the camera, and not with SD, as maybe is more common. I setthe pinmux to switch the pins (gpio_95 / gpio_96 / gpio_97 /gpio_98) tothe uart4, and ttyO3 is registered and available, and thanks your patchboth clocks iclk and fclk are active. However, I cannot see activity onthe tx line if I try to send some characters.
